Sure. > | |but since we run with -ww we > | |get the warning about an unbalanced .el > > That's a broken warning. Amen. But let's be honest, in this day and age *very* few people can can read troff, never mind write it (and I don't count myself as one), so a warning from groff, however broken, will just confuse and upset the users. Since silencing this warning doesn't require that much of an effort and doesn't mutilate the code that much, it's easier to just shut it up. -uwe
